The THRIVE study is a 3-arm longitudinal randomised controlled trial which will rigorously evaluate the efficacy of two parenting interventions, Enhanced Triple P for Baby and Mellow Bumps by comparing them against the routine care provided to vulnerable women during pregnancy (care as usual). This is a multi-component study which will collect the following data:

The trial will be conducted within a number of NHS approved locations within the NHS Greater Glasgow and Clyde and NHS Ayrshire and Arran Health Board areas. Visits will also be made to the woman’s homes for data collection.

The severity of any psychological distress across 9 dimensions will be measured using the Brief Symptom Inventory (BSI-53).
Health status will be measured using European Quality of Life – 5 dimensions scale (EQ-5D-3L), a generic measure of health, required for the economic evaluation.
Hospital Anxiety and Depression Scale enhanced by the outwardly–directed irritability questions from the Adult Wellbeing Scale (HADS+I).
Karitane Parenting Confidence Scale will be used to measure the mothers’ experiences of being a parent.
An evaluation questionnaire will be completed by each mother after each support group.
Practitioners will complete post-session evaluation forms and questionnaires on their expectations and experiences of taking part.
Long-term outcomes will be assessed by collecting data that is collected routinely as infants grow. These will be collected from measures such as the Strengths and Difficulties Questionnaire (SDQ) and the Sure Start Language Measure.

The research is led by Dr. Marion Henderson, and involves researchers based at the University of Glasgow, Glasgow Caledonian University, the University of Aberdeen, the University of Manchester and the University of Newcastle.
